DOUBLE-WALL WALL-BOARD CONSTRUCTION AND SPACING MEMBER THEREFOR.

Application filed December 2'1, 1625. Serial No. 76,662. I a

My invention relates to wall constructions using the well known wall or plaster board. In the usual form of wall construction using wall board, the wall board sheets are nailed 5 to the opposite sides of timber studs of the wall construction, whereafter a coating of plaster is applied to the exterior sides of the wall board sheets, thus finishing the wall.

{ Wall board partitions may be made very cheaply, without the use of studs, by employing vertical wallboard retaining members extended from the floor to the-ceiling, engaging side edges of the wall board sheets and holding them in place. Both sides of the wall board sheets aregiven a coating of plaster, thus forming a complete'partition.

Partitions of this character are 7 quite often used in place of wall constructions because of the factor of economy, althoughthey are not by far as satisfactory. PaItltions are not entirelysatisfactory because they are not wholly stable or sound-proof and do not have heat insulation characteristics to speak of. A large item of expense in wall constructions is the cost of installa- 7 'tion of the timber studs. v It is an object of my invention to provide a wall construction, using wall board, which does not require timber studs as a component.

It is another object of this invention 'to provide a novel form of spacing and bracing member for use-1n timberless wall constructions for the'purpose of properly spacing the opposing sheets of wall board and for bracing and rigidifying the wall construction. V

Other objects and advantages will be made evident hereinafter. Referring to thedrawing in which I illustrate a preferred formof my invention,

Fig. 1 is a perspective view showing a spacing member which performs an important function in the wall construction of my invention. Y Q Fig. 2 is a horizontal sectioned view ofa wall construction embodying the features of my invention. f I, r

Fig. 8 is a fragmentary view taken as :indicated by the arrow?) of Fig. 2. j 4 1 s Fig. 4 is afragmentary section taken on the line ofFig. 3. Referring. particularly to. Fig. 2, the wall construction of my invention consists ofa primary wall 11 and a secondary wall 12.

The Walls 11 and 12 are formed from' sheets ofwall members 14 which are in this case shown consisting of a web 16 which rests between the vertical faces of adjacent sheets of wall board and flanges 17 which extend from opposite edges of the web 16 in opposite directions and in positions to contact faces of the sheets of wall board 14.- The Vertical wall board retaining members 15 are substantially reverse Z-shape as shown in Fig. 2. Secured to the web 16 of the re taining members 15 are ears or tongues 19 which may be bent into the position shown in the drawing to cooperate with an opposite flange 17 for holding the wall board in place. 7 These vertically extending wall board retaining members ordinarily extend from the floor to the ceiling and retain the sheets of wall board 14 in a common vertical plane. In the past the wall board retainers 15 were 89 used only in single wall construction or partitions. I

The primary and secondary walls ll and 12 are held in proper parallel spaced relationship and are braced by spacing members 22. Referring to Fig. 1, each of the spacing members 22 consists of a U-shaped member having aweb or .back 23 from the opposite edgeslof which legs 24 extend in planes at right angles to the; web 23 andparallel to each other. Near each end 'ofeach of the spacing members 22 is aretaining channel 26 and extending outward from the vbottoms T of these channels at each side therefrom are wall board rest in the channels 2 6,- As

shown clearlyjin-Fig. 4 the retaining mem bers 22 are placed so I that corresponding horizontaledges of opposing sheets of wall oa re i nnel 26' o h same p cing member 22, The edge faces of the Wall boards rest against the portions of the web 23 which form the bottoms of the channels 26 and against the faces of the wings 27 which extend in the same plane as the engaged faces of the webs 23.. In practice the spacing members 22 are placed on the upper and lower horizontal edges of the opposing sheets of wall board 14 in staggered relationship as shown clearly in Fig. 3. Therefore the web portions 23 of the staggered spac' 1g members 22 rest in the same plane and therefore only a minimum gap is left between the adjacent horizontal faces of the sheets of wall board.

The channels 26 are of the same width as the thickness of a wall board or may be slightly narrowerso that the legs2 l may firmly grip the horizontal edges of the wall board. These members 22 not only retain the upper and lower horizontal edges of the sheet of wall board in proper spaced relationship, but tie the primary and secondary walls 11 and 12 together which makes them quite rigid. The wings 27 provide a large engagement face and contact with the hori zontal edge faces of the sheets of wall board and thus prevent any twisting whatsoever of the spacing members 22'.

A coating of plaster 32 is then applied to the exterior of each of the faces of the primary and secondary walls 11 and 12. In Fig. 2 only the secondary wall 12 is shown plastered. As shown in Fig. 1 the ends of the spacing members 22 extend from the exterior faces of the primary and secondary walls 11 and 12 and thus provide a tying means'for the plaster which assists in securing the plaster to the exterior faces and prevents creeping. From the foregoing description it is evident that my invention eliminates the use of t mber studs in double wall constructions, and makes it possible to provide a wall construction of this character much cheaper than has ever been produced. In place of the timber studs and the nailing of the sheets of wall board to the studs I employ the verti cally extending wall board retaining mem-.

bore and the spacing members 22 which are quite economical as compared with the timber studs and the nailing of the sheets of wall board in place.

I claim as my invention:

1. In a wall construction, the combination of: a primary wall composed of sheets of wall membersp a secondary wall composed of sheets of wall members, said secondary wall beingsp'aced directly adjacent to said primary wall and substantially parallel thereto; primary retaining members extending vertically between the vertical edges of the sheets of wall members of said primary wall,

engaging and retaining them in a commonverti'cal plane; n secondary retaining mem; bers extendingvertically between the 'ver essons tical edges of the sheets of wall members of said secondary wall, engaging and retaining them in a common vertical plane; and spacing members connected to said primary and secondary walls at points where the h0r izontal edges of the wall members of the respective walls meet.

2. In a wall construction, the combination of: a primary wall composed of sheets of wall members; a secondary wall composed of edges of the sheets of wall members of said secondary wall, engaging and retaining them in a common vertical plane; and spacing members having channels formed therein for receiving horizontal edges of the opposing sheets of wall members of said primary and secondary walls for spacing and bracing said walls.

3. In a wall construction, the combination of: a primary wall composed of sheets of wall members; a secondary wall composed of sheets of wall members, saidsecondary wall being spaced directly adjacent to said primary wall and substantially parallel thereto; primary retaining members extending vertically between the vertical edges of the sheets of wall members of said primary wall, engaging and retaining them in a co1nmon vertical plane; secondary retaining members extending vertically between the vertical edges of the sheets of wall members of said secondary wall; engaging and retaining them in a'common vertical plane; members for spacing'and bracing the opposing sheets of wall members of said primary and secondary walls, each of said members having spaced channels adapted to receive corresponding edgesof opposing sheets of wall members; and wings extending outward from the channels of said members, said wings ex- 7 tending in planes parallel to the horizontal edges of said sheets of wall members and in contact therewith.

4. In a wall construction, the combination of: a primary wall composed of sheets of wall members; a secondary wall composed of sheets of wall members said secondarywall being-spaced directly adjacent to said pri-' mary wall and substantially parallel thereto: primary retainingmembers extending vertically between the vertical edges of thesheets of wall members of said-primary wall, engagingand retaining them {in a common vertical plane; secondary retaning'members extending vertically between the vertical edges of the sheets-of wall, members'ot said which said wings consist of portions of said U-shaped members extended outward in order to provide said channels.

6. A spacing member for double wall board construction, said member comprising: an elongatedvU-shaped body providing a base wall and opposite parallel side walls, said side walls being slotted near their opposite ends to provide parallel transverse channelseach adapted to receive a wall board; and side Wings in the plane of said base wall and extending in opposite directions transversely and in alignment with the respective channels, the side walls between said channels serving as means for maintaining said wall boards in relative spaced relationship, and the side wall portions beyond said channels serving as means for retaining said wall boards against relative separation.

7. A spacing member for double wall board construction, said member comprising: an elongated U-shaped body providing a base walland opposite side Walls, said side walls being transversely slotted at relatively spaced intervals to provide parallel channels, and said base wall being extended in opposite transverse directions adjacent each channel to provide side wings. i

In testimony whereof, I have hereunto setmy hand at Los Angeles, California, this 15th day of December, 1925.
